My car was the first uk 350z in the country and some think its may have somthing to do with it ??
No i did not do i run before i fitted the K&N but i seamed to gain exactly the 10 bhp K & N state !!
Also people say that the ecu learns your driving style ?
I Allways wait til she's warm but after a few miles i have no probs taking it to the red line now and again ??
